Geo Edition is now world’s largest collection of historical GIS-enabled urban maps
May 18, 2010 (ANN ARBOR, Mich.) -- ProQuest is using a proprietary geo-referencing technology to significantly enhance discovery in its Sanborn Map collection, one of libraries’ most consulted sources of historical maps. ProQuest® Sanborn Maps Geo Edition makes map research faster by enabling users to instantly pinpoint historical locations using modern geographic information. The collection is now the world’s largest source of historical GIS-enabled urban maps.
“Sanborn Maps are the go-to historical U.S.maps in academic and public libraries. Now with this new geo-referenced content and layering technology, they are exponentially more useful for research,” said Chris Cowan, ProQuest, Vice-President. “The technology conquers traditional map research bottlenecks, where comparative reviews and data connections are difficult and time-consuming. This is a significant advancement for not only geographers, but social scientists, environmentalists, urban planners, and genealogists.”
Founded in 1867, the Sanborn Map Company was the primary American publisher of fire insurance maps for nearly 100 years. Popular among researchers because of their detailed descriptions of streets, buildings, and properties in U.S. towns and cities, the maps were digitized by ProQuest to make them more accessible and searchable. Now, the geo-referencing in ProQuest® Sanborn Maps Geo Edition overcomes the challenges of finding historic areas that have been renamed, remodeled or wiped away over time by enabling users to search and compare these locations using modern addresses, geographic coordinates and geographic maps.
Geo Edition includes a new search interface that enables users to access more than 60,000 geo-referenced maps, covering some of the most populous and historical cities in the United States. Maps can be viewed individually in greater detail with rotation, panning, cropping, and dynamic zoom in/out features. An integrated dynamic overlay map viewer allows maps to be compared and contrasted over time with multiple maps from the same city and against modern day street, satellite, and hybrid views. Geo Edition also connects with other geo-spatial content through GeoTIFF files that can be used to import data into the map files.
Geo Edition is an all-new product that’s available through subscription or permanent site license. Learn more at www.proquest.com. It is part of ProQuest’s larger initiative to continually innovate with technology, unlocking the full potential of legacy research tools.
